=================== ===================
Metrics of rpcdetailed context are exposed in unified manner by RPC layer. Two metrics are exposed for each RPC based on its name. Metrics named "(RPC method name)NumOps" indicates total number of method calls, and metrics named "(RPC method name)AvgTime" shows average turn around time for method calls in milliseconds. Metrics of rpcdetailed context are exposed in unified manner by RPC layer. Two metrics are exposed for each RPC based on its name. Metrics named "(RPC method name)NumOps" indicates total number of method calls, and metrics named "(RPC method name)AvgTime" shows average processing time for method calls in milliseconds.
Please note that the AvgTime metrics do not include time spent waiting to acquire locks on data structures (see RpcLockWaitTimeAvgTime). Please note that the AvgTime metrics do not include time spent waiting to acquire locks on data structures (see RpcLockWaitTimeAvgTime).
Metrics named "Overall(RPC method name)AvgTime" shows the average overall processing time for method calls
in milliseconds. It is measured from request arrival to when the response is sent back to the client.
